Hi mackrackit, I was able to run the RTC on PortB.0(SCL) and PortB.1(SDA). I'm still confused. I tried PortA ports that has TTL but did not work. and I have read other thread that they were able to run their program using Pic16F877A to read RTC module on PORTC.1 and PORTC.0 (Post# 1 http://www.picbasic.co.uk/forum/showthread.php?t=12671) can you help me point out how it works? I'm amazed that my lcd is also using PortB.0 and PortB.1 at the same time with the RTC required pins. BTW now I'm on Pic16F877A, does this mean that my sdcard module will not work on this chip?

thanks for the patients,
tacbanon
